— Find a lisp keyword
char * name
Many Lisp functions take keyword arguments. When invoking a function with keyword arguments we need keywords, which are a kind of symbols that live in the
KEYWORD package. This function does the task of finding or creating those keywords from C strings.
It is usually safe to store the resulting pointer, because keywords are always referenced by their package and will not be garbage collected (unless of course, you decide to delete it).
Remember that the case of the string is significant.
ecl_make_keyword("TO") with return
ecl_make_keyword("to") returns a completely different keywod,
:|to|. In short, you usually want to use uppercase.
